Abstract

Disclosed is a fuel cell-based multiple power supply system, and more particularly a fuel cell-based multiple power supply system capable of alternately operating a polymer electrolyte membrane fuel cell that is rapidly started up and provides fast response and a solid oxide fuel cell that provides high power generation efficiency depending on required situations and remedying some power deficiency using an energy storage system or a secondary battery, such as a super capacitor, thereby flexibly dealing with a situation difficult to solve using a single fuel cell.
